This paper describes the results of a preliminary study on the applicability of the command-response model to F0 contours of spoken Hindi, an official language of India with almost 400 million native speakers in the world. Analysis of observed F0 contours of a number of utterances by two native speakers indicated that the model with provisions for positive and negative accent commands applies quite well to all the utterances analyzed, and the estimated commands are found to be closely related to the linguistic contents of the utterances. One of the peculiar features of F0 contours of Hindi is the occurrence of a negative accent command at most phrase-initial positions, often followed by a positive accent command.
